K19008AR0 Bearing Product Overview & Core Advantages
The K19008AR0 is a thin-section angular contact ball bearing designed for applications demanding high precision and space optimization. As part of the Reali-Slim mm Metric series, it features a single-row design with a 30° contact angle, enabling it to efficiently support combined loads (simultaneous radial and axial loads). Its compact cross-section, with a width of only 8 mm, makes it an ideal solution for lightweight, high-rigidity systems where saving space and weight is critical. Manufactured to ABEC-1 precision tolerances, this bearing ensures reliable performance in precision mechanisms.
K19008AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a specific bearing series or prefix (Reali-Slim Metric series). |
| 19008 | Specifies the bore diameter (190 mm) and the cross-sectional size code. |
| A | Denotes a 30° contact angle, optimized for high axial load capacity. |
| R0 | Specifies the radial internal clearance group (C0 standard clearance). |
K19008AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The bearing's exceptionally slim 8mm width and large 190mm bore provide a high stiffness-to-weight ratio, crucial for high-rigidity support in compact assemblies.
Superior Load Capacity: The 30° contact angle and single-row construction are engineered to handle significant combined loads, offering a high axial static load rating of 4164 lbf alongside its radial capacity.
Precision Engineering: Manufactured from chrome steel for rings and balls with a brass cage, and built to ABEC-1 tolerance standards, ensuring smooth operation, minimal vibration, and extended service life in precision applications.
Standard Lubrication & Open Design: The bearing comes pre-lubricated and features an open seal type, allowing for custom lubrication regimes to suit specific operational speeds and temperature ranges (-30°C to 110°C).
K19008AR0 Bearing Typical Application Areas
- Robotics: Joint and arm assemblies requiring compact, high-precision bearings.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms where weight and space are constrained.
- Medical Equipment: Surgical robots, imaging devices (CT/MRI scanners), and diagnostic instruments.
- Semiconductor Manufacturing: Precision stages, wafer handling robots, and other cleanroom automation equipment.
- Industrial Automation: Rotary tables, indexing heads, and other high-accuracy positioning systems.
